LC meter with PIC16F870

This projects talks how to build an inductance and capacitor measuring tool based on PIC16F870 microcontroller. On the project’s page you can also learn about the theory behind measurements and how microcontroller calculates inductance and capacitance. Main hardware of the consists of a common LCD display, PIC16F870 mcu and LM311 oscillator. Design details, schematics, software and PCB can be found on the link below. Expected accuracy is +/- 1% of reading +/- 0.1pF or +/- 5nH
